Since their 2011 wedding, Prince William and wife Catherine have embarked on two tours, which has seen them visit Canada, United States and South-east Asia.

However, speaking today, private secretary Jamie Lowther-Pinkerton to the Duke and Duchess, said William and Kate would be focussing on their family life this year and a view on royal tours will be “assessed” later on.

This year will be an important year for the royal couple, as in July they will welcome their first child. The royal baby will become third in line, after Prince Charles and Prince William, and will one day become the King or Queen.

Secretary Lowther-Pinkerton continued that the pair will be unable to tour overseas during to Catherine’s pregnancy. He said: “I’m not anticipating the Duke and Duchess taking on overseas tours because of her baby.”

While it has been suggested that it is “highly unlikely” that the couple will take on a tour, it has not been ruled out that the Prince will make a visit solo.

Despite being almost six months pregnant, The Duchess of Cambridge has continued to work. Catherine, last week joined Her Majesty The Queen and The Duke of Edinburgh to celebrate 150 years of the Underground, at Baker Street Station. During the visit she was given a “baby on board” badge and revealed she missed taking the tube.

While it is unlikely there will be a overseas this year, it is suspected that Prince William and The Duchess of Cambridge will tour in 2014, with Ireland and Australia both being heavily rumoured.

During their 2012 Diamond Jubilee tour of South-east Asia, a French magazine decided to print personal photos of the Duchess, taken on a private holiday. At the time, St. James’s Palace released a statement saying the Duke and Duchess of Cambridge were angry and sad at the intrusion of privacy. As the news broke, the royal couple visited a mosque in the centre of Kuala Lumpur, Malaysia, and focused on the rest of their tour.

Along with two tours on behalf of Her Majesty, Prince William and The Duchess of Cambridge also joined Crown Prince Frederik and Princess Mary of Denmark, in November 2011, in Denmark. The two royal couples toured UNICEF’s global crisis center in the Danish capital.
